ANH Refractories is a family of companies including APGreen, North American Refractories Co., and Harbison-Walker. Together, they provide high-temperature refractory products for several industries, including energy, glass, and iron & steel. Here at The Ceramic Shop, we offer several of their products which are necessary for kiln building and maintenance, including various types of Inswool, fire bricks, and refractory mortar. Because we can dedicate space in our large Philadelphia warehouse to these items, we can buy in quantity, just like a construction business. This means that we are able to sell these items to you in smaller, more manageable volume sizes! Please don’t hesitate to get in touch if you have any questions about the wide variety of refractory materials offered here at The Ceramic Shop – our knowledgeable staff can direct you to a product that will work for your project.
